HCID 178449181HCID 178449181, compoundYield 96.7%

Procedure

A mixture of 33 g of N-butylamine (0.45 mol) and 19 g of diisopropylcarbodiimide (0.15 mol) is refluxed for 3 h 30. GC analysis then shows a conversion of greater than 99.5% of the diisopropylcarbodiimide. The colorless final mixture is concentrated at 60° C. under 20 mbar for 2 h so as to give 29 g of a colorless and virtually odorless liquid of low viscosity, corresponding to the expected guanidine (yield 96.7%).
